Layout

Show/Hide

'Show ThreadSearch toolbar': clear enough, isn't it ??

'Show search widgets in ThreadSearch Messages panel.': if checked, only the results list control and the preview editor are displayed. All other search widgets are hidden (spares space).

'Show code preview editor': Code preview can be hidden either with this check box or with a double click on the splitter window middle border. This is where it can be shown again.

List control options

'Display header in log window': if checked, the header are displayed in the results list control. Be careful ! if unchecked, the columns are no longer resizeable but space is spared.

'Draw lines between columns': clear enough, isn't it ??

'ThreadSearch panel management by': the ThreadSearch panel can be managed either by the layout (docking support) or the Messages notebook (ThreadSearch panel is one of the pages)

'Logger type': results can be displayed in a list control (each line is a result with directory, file, line number and matching text) or a tree (each node is a file path, each sub node is a matching text + line number).
